Allow launching only one tutorial in touchpad/keyboard tutorial

Now INTENT_TUTORIAL_SCOPE_KEY can be used to start only single tutorial for contextual education. Compared to regular flow which always show all tutorials available for given peripheral.

Two main changes:
1. Renaming INTENT_TUTORIAL_TYPE_KEY to INTENT_TUTORIAL_SCOPE_KEY
2. Adding ScreenSequence which determines if we should follow natural screen order or finish after first screen.
